[0001] The utility model relates to the technical field of barite slurry, in particular to a drying device for barite slurry used for preparing barite powder. Background Technique
[0002] Barite is the most common mineral of barium, and its composition is barium sulfate. It is produced in low-temperature hydrothermal veins, such as quartz-barite veins, fluorite-barite veins, etc., and is often symbiotic with galena, sphalerite, chalcopyrite, cinnabar, etc. The barite deposits produced in Hunan, Guangxi, Qinghai, and Jiangxi in China are mostly huge hydrothermal single-mineral veins. Barite can also be produced in sedimentary rocks, appearing in the form of nodules, mostly existing in sedimentary manganese deposits and muddy and sandy sedimentary rocks in shallow seas. In the residual clay covering layer of weathering residual deposits, it often occurs in nodular and massive forms.
[0003] In the process of preparing barite powder, the drying of barite slurry is an important step to ensure the stability of subsequent processing and the improvement of product quality. When drying barite slurry, the slurry needs to be poured into a stirring barrel for stirring and heating. When heating, only one side of the barrel can be dried, resulting in uneven drying of the middle part inside the slurry. Content of the Utility Model

Specific embodiments
[0022] To further elaborate on the technical means and effects adopted by the present utility model to achieve the predetermined utility model purpose, the following will, in conjunction with the accompanying drawings and preferred embodiments, detail the specific embodiments, structures, features and their effects of the present utility model as follows.
[0023] Please refer to Figures 1-4 As shown, a barite slurry drying device for barite powder preparation includes a bottom plate 1. Both sides of the top of the bottom plate 1 are fixedly connected with vertical plates 2. A stirring barrel 3 is rotatably connected inside the vertical plates 2. A heating box 9 is arranged at the bottom of the stirring barrel 3. A first motor 14 is fixed on the outer side of the left vertical plate 2. The output shaft of the first motor 14 is bolted with a first gear 15. A second gear 16 is meshed with the top of the first gear 15. The inside of the second gear 16 is fixed to the surface of the rotating shaft at the left end of the stirring barrel 3. A folded plate 5 is fixedly connected to the top of the stirring barrel 3. A rotating pipe 6 is rotatably connected inside the folded plate 5. The other end of the rotating pipe 6 penetrates through the stirring barrel 3 and extends into the heating box 9. A plurality of stirring pipes 7 are communicated with the surface of the rotating pipe 6. A driving structure 8 for driving the rotating pipe 6 to rotate is arranged at the top of the folded plate 5. An air inlet groove 10 is opened at the bottom of the heating box 9. A fan 11 is arranged inside the air inlet groove 10. Heating wires 12 are fixed on both sides of the inner cavity of the heating box 9. A connecting pipe 13 is communicated with the rear of the heating box 9. The other end of the connecting pipe 13 is rotatably connected to the top of the rotating pipe 6.
[0024] The driving structure 8 includes a second motor 81, a first bevel gear 82 and a second bevel gear 83. The second motor 81 is fixed on the top of the folded plate 5. The output shaft of the second motor 81 is fixed to one side of the first bevel gear 82. The inside of the second bevel gear 83 is fixed to the surface of the rotating pipe 6. One side of the second bevel gear 83 is meshed with one side of the first bevel gear 82. Thus, when driving the rotating pipe 6 to rotate, the second motor 81 can be started to drive the first bevel gear 82 to rotate, and at the same time drive the second bevel gear 83 and the rotating pipe 6 to rotate, thereby driving the stirring pipes 7 to stir the slurry, and further improving the subsequent drying effect.
[0025] Fixed rods 18 are fixedly connected to the upper and lower sides of both sides of the rotating tube 6. The other ends of the fixed rods 18 are fixedly connected to a scraping plate 19. The outer side of the scraping plate 19 is in contact with the inner wall of the stirring barrel 3. In this way, as the rotating tube 6 rotates, the fixed rods 18 and the scraping plate 19 can be driven to rotate together, so as to scrape the inner wall of the stirring barrel 3.
[0026] A cover plate 4 is hinged to the top of the stirring barrel 3. An expansion rod 17 is hinged between the inside of the folded plate 5 and the top of the cover plate 4. In this way, the cover plate 4 can be automatically opened and closed to facilitate subsequent feeding and pouring.
[0027] A dust-proof net 20 is arranged inside the air inlet groove 10. The dust-proof net 20 is located below the fan 11. In this way, impurities in the external air can be filtered to prevent dust from entering the inside of the heating box 9.
[0028] One end of the connecting pipe 13 is communicated with the top of the rotating tube 6. An exhaust hole is opened at the top of the stirring barrel 3. In this way, it is convenient for heat to enter the inside of the rotating tube 6 through the connecting pipe 13. At the same time, the heated gas inside the stirring barrel 3 will be discharged through the exhaust hole.
[0029] Working principle: When in use, the cover plate 4 can be driven to turn over by the expansion rod 17, and then the slurry is poured into the inside of the stirring barrel 3. When drying, the air inside the heating box 9 can be heated by the heating wire 12. When heating, the fan 11 can be started to make the fan 11 rotate slowly. In this way, it is convenient for the heat to be at the bottom of the stirring barrel 3 to facilitate heating the bottom of the stirring barrel 3. Then, the air pump 21 can be started, and the hot air inside the heating box 9 can be adsorbed. Subsequently, it will enter the inside of the rotating tube 6 through the connecting pipe 13. The heat inside the rotating tube 6 will enter the stirring tube 7. At the same time, a part of it will also enter the inside of the heating box 9. Then, driven by the driving structure 8, the rotating tube 6 can be driven to rotate, and the stirring tube 7 can be driven to rotate together, so as to facilitate uniform drying of the slurry. After drying is completed, the first motor 14 can be started to drive the first gear 15 to rotate, and at the same time drive the second gear 16 to rotate together, and then drive the stirring barrel 3 to deflect together. When deflecting, the expansion rod 17 can be restarted, and the cover plate 4 can be opened to perform discharging treatment.

Although the present utility model has been disclosed above with the preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some changes or modifications to equivalent embodiments by using the disclosed technical content without departing from the technical solution of the present utility model. However, as long as it does not depart from the technical solution content of the present utility model, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present utility model still fall within the scope of the technical solution of the present utility model.
